    Rule Details

    This rule enforces that each file may contain only a particular number of classes and no more.

    class Foo {}

    Options

    This rule may be configured with either an object or a number.

    If the option is an object, it may contain one or both of:

    • ignoreExpressions: a boolean option (defaulted to false) to ignore class expressions.
    • max: a numeric option (defaulted to 1) to specify the maximum number of classes.

    Examples of correct code for this rule with { "max-classes-per-file": ["error", 2] }:

    { "max-classes-per-file": ["error", 2] }
    class Foo {}
class Bar {}

    Examples of correct code for this rule with { "max-classes-per-file": ["error", { "ignoreExpressions": true }] }:

    { "max-classes-per-file": ["error", { "ignoreExpressions": true }] }
    class VisitorFactory {
  forDescriptor(descriptor) {
    return class {
      visit(node) {
        return `Visiting ${descriptor}.`;
      }
    };
  }
}
